public interface Term

Terms include Values, Events, and Patterns. Patterns are the only terms that can include variables. The separation is necessary to enforce constraints on values (for example, values can be serialized in a trace file but pattern variables cannot), and also because it makes the binary-dispatch nature of unification more straightforward to implement. However it does lead to some duplication of boilerplate code and class hierarchies.
